Renewable energy


Solar energy is inexhaustible, the cleanest and most common of all renewable energy sources, while one of the most elegant technologies available for its efficient use is photovoltaic technology. Respecting modern research trends in the field of renewable energy sources, the Center for Green Technologies conducts research aimed at studying and developing the latest generation of solar cells.

Classification of existing types of solar cells

One direction of our research is based on the synthesis, characterization and processing of nanostructured titanium(IV)-oxide for use in solar cells with photosensitive dye (dye-sensitized solar cells). This type of cell is an alternative to conventional and commercialized devices based on crystalline and amorphous silicon, cadmium telluride and pseudo-ternary compounds of copper, indium, gallium and selenium.

On the other hand, from the aspect of renewable and clean energy, one of the most important applications of solar cells is their use as photovoltaic materials integrated into buildings (building integrated photovoltaics, BIPVs). Using BIPVs, buildings are transformed from consumers into energy producers, with the ultimate goal of building an energy efficient building that would produce electricity using solar cells integrated into the building envelope (roof, facade, skylights, sunshades, canopies, domes, etc.). A group of researchers from the Institute for Multidisciplinary Research is developing new BIPVs materials, which are used in the upgrade of light and decorative building elements, such as plasticized aluminum sunshades.

Previous research in the field of solar cells has been realized through the following projects:



“0-3D nanostructures for application in electronics and renewable energy sources: synthesis, properties and processing”, Ministry of Education, Science and Technological Development of the Republic of Serbia (2011-2020), project manager Dr. Goran Brankovic.

2020-2022. Proof of concept no. 5706, “Aluminum sunshades with photovoltaic characteristics”, project manager: Dr. Katarina Vojisavljević, financing: The Innovation Fund of the Republic of Serbia.

2019-2020. Innovation voucher no. 538, “Testing of modification of materials for plasticization of Al-profiles for obtaining photovoltaic coating”, project manager: Katarina Vojisavljević, PhD, financing: The Innovation Fund of the Republic of Serbia.


Within the Laboratory of the Department of Materials Science, a complete experimental line for the production of solar cells with photosensitive dye has been developed, which enables various synthetic procedures and techniques for applying thick films, and their photovoltaic characterization. Thanks to that, cooperation with other scientific research organizations and economic entities has been developed, and the results of the research have been presented in international journals and at many international conferences:
